Cost-Effectiveness of Interventions for Driving While Intoxicated
Which Behavioral Interventions are Most Cost-Effective in Reducing Drunk Driving?
Policymakers have known for decades that consuming alcohol before driving can be a recipe for ruin. In 2013, for example, approximately 31 percent of all
motor vehicle–related fatalities involved drivers with blood alcohol concentrations (BACs) at or above the legal limit of 0.08. For many people, a BAC of 0.08 equals just two or three drinks over the course of an hour. These two or three drinks could be enough to seriously impair vision, hearing, reaction time, and attention.
What has been unclear is how to best allocate funds to reduce the problem of drunk driving. Many interventions are available to lawmakers, ranging from sobriety
checkpoints where law enforcement officers check random drivers for intoxication to alcohol ignition interlocks in individual cars. But given limited budgets, how
can policymakers know which available policies would reduce the most drunk driving–related deaths for their implementation dollars?
An interactive online calculator, designed by RAND Corporation researchers with funding and technical support from the Centers for Disease Control and
Prevention (CDC)’s National Center for Injury Prevention and Control and the Robert Wood Johnson
Foundation and hosted by the CDC, can help decisionmakers measure the cost-effectiveness of several driving while intoxicated (DWI) intervention policies
that are not in widespread use. The Motor Vehicle Prioritizing Interventions and Cost Calculator for States (MV PICCS) is designed around a critical policy
concept: Individual states have different safety intervention needs. Drunk driving is a larger problem in some states than it is in others, so states would benefit from
different types of policies. For example, the percentage of crash deaths attributed to drunk driving is 19 percent in Iowa and 48 percent in North Dakota. Because
drunk driving causes almost half the traffic fatalities in North Dakota, this state would likely want to focus on implementing stronger drunk driving policies more
than states where the proportion of drunk driving fatalities is low. MV PICCS gives users the ability to understand the impact that different intervention
policies might have in a state, then calculate the costs of implementing each intervention. The tool also allows the user to see how many lives could be saved
and injuries prevented from implementing different interventions.
In this research brief, we demonstrate how the data underlying MV PICCS can be used to show the value of implementing drunk driving policies nationally and
which interventions might be the most cost-effective from a national perspective. You can explore costeffective solutions for your own state by using MV
PICCS at www.cdc.gov/motorvehiclesafety/calculator.
Which Drunk Driving Interventions Work Best Overall?
Numerous interventions are available to policymakers.
For this exercise, we focus on five related to drunk driving that have proven effective; most have been adopted in fewer than half the states in the United
States. (Note: MV PICCS considers six DWI interventions in its analysis. We omit one of the interventions, saturation patrols, from this short analysis
because it was difficult to ascertain where this intervention is already in place.) The five are:
•
a device that prevents
a vehicle from starting until the driver has blown
into a tube to prove sobriety
• Sobriety checkpoint: a place where a team of
police officers stops cars to check whether drivers
are intoxicated
• License plate impoundment: requirement that a
driver convicted of DWI surrender the license plate
of his or her vehicle
• Limits on DWI diversion and plea agreements:
rules that prevent DWI arrestees from diverting
cases or pleading out of charges
• Vehicle impoundment: confiscation of a DWI
offender’s vehicle for a period of time, after which
the offender either reclaims or surrenders his or her
vehicle.

Cost-Effectiveness Ratio: How Much
Does It Cost to Save a Life?
MV PICCS uses cost-effectiveness to compare interventions. For every intervention, the tool contains two
pieces of information: the effect of implementing the
intervention and how much implementation would
cost the state. The effect is the value, expressed in
dollar terms, of the expected lives saved and injuries
Key Findings
• Different states have different needs when it comes to
drunk driving interventions.
• A new tool, Motor Vehicle Prioritizing Interventions and
Cost Calculator for States, can help decisionmakers
measure the cost-effectiveness, for different states, of
intervention policies to reduce driving while intoxicated.
avoided thanks to the intervention.*1The costs are
the costs to the state associated with implementation.
These costs include such things as police time, time
for department of motor vehicles (DMV) staff, and
additional equipment. The ratio of effect to cost is the
cost-effectiveness ratio: The higher the ratio, the more
cost-effective the intervention. The cost-effectiveness
ratio in this case is the monetized value of the lives
saved and injuries prevented relative to how much the
intervention would cost a state.
Implementing All Drunk Driving Policies
in All States Is Effective but Expensive
If all five DWI interventions were implemented in
states that do not currently have them, the United
States would see 1,182 lives saved annually. The
annual cost would be about $764 million, and the
monetized value would be $2.7 billion. The costeffectiveness ratio of this approach is 3.53, meaning
that, on the whole, society gets $3.53 of benefit for
every $1 spent by the state to implement the interventions. Although this is a positive cost-effectiveness
ratio, other ways of reducing drunk driving might be
even more cost-effective. To determine this, we need
to look for specific interventions with higher costeffectiveness ratios.
Why State-Specific Analysis Is Needed
The same intervention can have different costeffectiveness ratios in different states. This is due to
differences across states in effects and costs. The effects
of implementing an intervention depend on the distribution of crash causes (the proportion of crash deaths
caused by DWI varies from state to state) and the
value of saving a life or avoiding an injury. The costs
* This is a typical way of measuring the benefit of any policy
whose goal is to save lives or reduce harm. The value of saving
one life is based on such things as medical costs, lost wages, and
emergency services. The project documentation explains how we
calculated these costs. See Jeanne Ringel, Johanna Zmud, Kathryn
Connor, David Powell, Brian Chow, Liisa Ecola, Christina Panis,
and Gregory Jones, Project Report and User Guide, Atlanta, Ga.:
Centers for Disease Control and Prevention, October 2014.

depend on the cost to implement an intervention,
which varies from state to state because of differences
in such items as wages paid to state employees, population, and size. Costs also vary based on the assumed
number of offenders in each state (that is, costs to
implement a drunk driving intervention are based on
the number of offenders).
If we want to find the most cost-effective interventions, we need to look at the cost-effectiveness of
each intervention in each state, then rank them. We
do not want to include in the analysis those interventions that are already in use. There are 255 possible
intervention-state combinations (51 states times five
interventions); if we exclude those that are already in
use, we end up with 119.
The figure on the next page shows these 119 combinations in declining order of their cost-effectiveness
ratios.
Each blue dot represents one combination. In general, because a policy with a cost-effectiveness ratio less
than 1 has costs outweighing benefits, policymakers
would avoid those policies. If they want to maximize
the safety gains from the dollars allocated for traffic
safety, policymakers should start with the combinations with the highest cost-effectiveness ratios.
The figure shows that the cost-effectiveness ratio
curve declines rapidly because only a handful of
combinations have very high cost-effectiveness ratios.
In 10 cases, the cost-effectiveness ratios exceed 100.
In 24 cases, the ratios are less than 1. Although
there is nothing particularly significant about a
cost-effectiveness ratio of 100, if policymakers start

Number of combinations
by implementing those 10 policies, they will do a
better job of maximizing the impact of traffic safety
spending.
Of the 10 combinations (policy implemented in a
particular state) with the highest cost-effectiveness
ratios, five are license plate impoundment and
five are alcohol interlocks. These rank high in costeffectiveness terms because they are sanctions that take
place after arrest and thus do not impose additional
costs to the police or court system. Also, offenders are
required to purchase the interlocks, which means the
cost to the state is low.
The total cost of implementing these 10 cases is
$2.1 million, and they would save 170 lives. That
works out to a collective cost-effectiveness ratio of 167.
Table 1 compares the costs and effects of implementing these 10 combinations with the highest
cost-effectiveness ratio and all 119 combinations.
State-Specific Analysis in Action
This exercise was designed to show that states vary
in the costs and effects of each combination, and
interventions that might be highly cost-effective
in one state might be less so in another. If budgets

are limited, the most cost-effective way to reduce
DWI deaths and injuries is to select the most costeffectiveness interventions regardless of state. Table 2
shows the 10 most cost-effective combinations. The
data show the number of lives possibly saved and
the benefit of saving these lives in terms of dollars,
the cost of implementing the policy, and, finally,
the cost-effectiveness ratio—the number of lives saved
and injuries prevented relative to how much the
intervention would cost a state. Of course, the tool
cannot tell decisionmakers whether they should
implement a particular DWI policy. The information
provided by the tool can guide decisionmakers in
figuring out which policies stand to save the most
lives and how much policies would cost the state
and taxpayers.
